Asr 5 sizing help

Little help with ASR5 sizing, please. I normally ride mediums and I'm currently on a MotoLite. The medium asr5 seems a bit longer than what I'd normally ride. Im 5'8 with a 32" inseam so a little bit longer in the legs than most but only by a tad. I prefer not to have my seatpost well above my bars and a Med frame generally helps with this. However, the Small frames have almost the same seat tube length so I'm I. Between sizes and undecided.

Also, I run a 70mm stem and 720 bars so I could just drop to a 60mm stem if needed.
